[QUOTE="PSG-1, post: 289216, member: 6937"] Correct. It could indeed pose a problem, if the boat is not maintained properly. It's more of an issue in saltwater, and this is why I always recommend my customers have me install a zinc anode on the hull of their boat, at the transom. The zinc should also be connected to a bonding wire, attached to the bonding wire of the engine, or directly to the negative terminal of the battery. Also, when using an aluminum boat in saltwater, it's a good idea to have a coat of suitable primer and bottom paint, such as Interlux Trilux 33. A coat of interprotect primer should be used before applying the antifouling paint, as it is rated for use below the waterline on all metals, it is a 2 part epoxy. WARNING! DO NOT USE CUPROUS OXIDE-BASED ANTIFOULING PAINT, IT WILL DESTROY THE HULL WITH ELECTROLYSIS. Use Cuprous Thiocyanate-based antifouling paint anytime it is in contact with aluminum. Keep the bottom paint in good shape, maintain the zincs, and you can keep an aluminum boat in saltwater throughout the year, with no ill effects from electrolysis. [/QUOTE]
